Choosing the right kind of footwear is very important. you cant choose something in which are not comfortable by any means. choosing footwear should always be based on comfort and the right size. fashion and trendy appearance comes later.
COMFORTABLE FOOTWEAR this is first rule one should follow in choosing choose a footwear. your foot needs to feel comfortable.
SIZE choose a sandal that fits your foot. see to it the strap of the sandal is too tight because it may hurt and cause severe pain to your foot. in shoes there should be little space between your toes and the shoes. wear socks while using shoes
RIGHT FOOT WEAR FOR RIGHT OCCASION before buying a shoes you need to be clear for which occasion it would be used, for example if you going for jogging - choose jogging shoes and trekking shoes. one needs to be clear about the occasion and choose the right shoes accordingly.
HIGH HEELS some prefer to wear sandals with heels and for those I suggest you dont buy stilettos. they wont last for longer period and you end up straining and hurting your ankle. instead go for wedge sandals or sandals with spool heels.
